Lodging studies inLolium perennegrown for seed: 1. Seed yield and seed yield components

The Journal of Agricultural Science, 1978
SummaryThe effects of lodging on the seed yield of S. 23 and S. 24 perennial ryegrass were investigated in a series of field experiments from 1973 to 1976. Natural lodging severely reduced seed yield in all years as a result of a decrease in the number of seeds per unit area.

THE INFLUENCE OF SEED SIZE AND SEEDING RATE ON YIELD AND YIELD COMPONENTS OF BARLEY

Canadian Journal of Plant Science, 1963
Field experiments with three seed sizes and three seeding rates of each of three barley varieties were conducted in 1959 and 1960 at Edmonton and Lacombe, Alberta. Data were obtained on emergence, culm counts, grain yields, and 1000-kernel weights.

Hulless Barley Seeding Rate Effects on Grain Yield and Yield Components

Crop Science, 2009
ABSTRACTRecent efforts to expand markets for winter barley (Hordeum vulgare L.) in the mid‐Atlantic have focused on hulless types due to higher energy density. The exposed endosperm of hulless barley makes damage more likely than with hulled barley, and emergence is typically lower.

Partitioning Soybean Seed Yield Components¹

Crop Science, 1982
Little is known about the nodal distribution of seed yield components in short‐seasoned soybeans [Glycine max (L.) Merr.]. This study was initiated to determine the effect of row width and plant density on the seed yield and yield components at each node of ‘Evans,’ a group O soybean cultivar. Field trials were planted in late May 1979 and 1980. The 25,

Effects of Clipping on Red Clover Seed Yields and Seed‐Yield Components¹

Crop Science, 1966
The effects of clipping on seed yields and seed‐yield components of four red clover varieties were determined from 1962 to I965 on 2nd‐ and 3rd‐year stands. The varieties ‘Altaswede,’ ‘Dollard,’ ‘Kenland,’ and ‘Pennscott’ were selected to provide a range of types froln single‐cut to double‐cut. Unclipped plots and plots clipped on May 1 produced higher

Sowing date affects yield components of canarygrass seed

Canadian Journal of Plant Science, 2003
Canarygrass (Phalaris canariensis L.) crops are sown from June to mid-September in the southeastern area of the province of Buenos Aires, Argentina. Sowing dates in this range result in different growing temperatures and photoperiods that affect the duration of developmental stages, biomass production, and seed yield and its components. For Argentina,

How Does Seed Vigor Affect Soybean Yield Components?

Agronomy Journal, 2018
Core Ideas Plants originated from the high‐vigor seeds presented more efficiency on nitrogen fixation. Low vigor levels resulted in higher yield variability among plants. Plants grown from high vigor seeds exhibited higher yield. Several factors may limit the germination, growth, development, and productivity of soybean [Glycine max (L.) Merrill]. Thus,

Influence of alfalfa seed belts on yield component and seed yield in mainland China - A review

LEGUME RESEARCH - AN INTERNATIONAL JOURNAL, 2019
Alfalfa is widely cultivated, and the seed yield differs in different regions due to the climate environment and so on in China. In order to obtain higher yield, alfalfa seed production must choose the most suitable area. Therefore, according to the geographical and climatic conditions, the alfalfa seed production area can be divided into four belts ...

Evaluation of seed yield and seed yield components in red–yellow (Pisum fulvum) and Ethiopian (Pisum abyssinicum) peas

Genetic Resources and Crop Evolution, 2012
Red–yellow (Pisum fulvum Sibth. et Sm.) and Ethiopian (Pisum abyssinicum A. Br.) peas have become of increasing interest to breeders in the last decade, as they have been found to be partially or completely tolerant to various biotic stresses, such as to attack by pea weevil, mildew blight or rust.

Seed Yield Components in Lentils¹

Crop Science, 1974
A yield component study of 45 lentil (Lens esculenta Moench) cultivars was conducted to determine the interrelationships between yield and yield components and to develop a selection procedure that would take into account important yield components and give special attention to seed weight.
